AS/400
<computer> An IBM minicomputer for small business and departmental users,
released in 1988 and still in production in October 1998.
Features include a menu-driven interface, multi-user support, terminals that are
(in the grand IBM tradition) incompatible with anything else including the IBM
3270 series, and an extensive library-based operating system.
The machine survives because its API layer allows the operating system and
application programs to take advantage of advances in hardware without
recompilation and which means that a complete system that costs $9000 runs the
exact same operating system and software as a $2 million system. There is a
64-bit RISC processor operating system implementation.
Programming languages include RPG, assembly language, C, COBOL, SQL, BASIC, and
REXX. Several CASE tools are available: Synon, AS/SET, Lansa.
